Description
When you’re out in the field and hear that grinding noise coming from your disc harrow or tillage equipment, you know it’s time for new bearings. A worn disc bearing doesn’t just make noise—it creates uneven tillage, increases fuel consumption, and can lead to more expensive shaft damage if you let it go. This NTN disc bearing gets your equipment back to cutting through residue smoothly instead of bouncing across the field.
What You’re Getting
- Greasable design lets you maintain it instead of running it until it fails
- 1-1/8 inch square bore fits standard disc gang shafts perfectly
- Spherical outer race handles the side loads and impacts of field work
- Built to NTN’s agricultural bearing standards for long service life
- 80mm outer diameter provides the load capacity needed for tillage operations
Built for Real Farm Work
This bearing is designed for disc harrows, utility discs, and other tillage equipment that use 1-1/8 inch square axles. Whether you’re breaking up compaction after harvest, incorporating crop residue, or preparing seedbeds for planting, this bearing handles the punishment that comes with cutting through tough field conditions.
Made to Last
NTN builds these bearings specifically for agricultural applications where dirt, moisture, and heavy loads are part of the job. The greasable construction and quality seals keep contamination out while letting you add fresh grease to extend bearing life well beyond what sealed units offer.
Installation Notes
Pack the bearing with quality disc bearing grease—not general purpose grease. While you’ve got the gang apart, check the shaft for wear where the bearing rides, and inspect the other bearings since they typically wear at similar rates. Mark gang positions before disassembly to maintain proper disc spacing when you put it back together.
